Technical Field

[0001] The utility model relates to the technical field of pipe cutting machines, in particular to a planetary pipe cutting machine. Background Art

[0002] Steel pipes have hollow cross-sections, and their length is much greater than the diameter or circumference of the steel. According to the cross-sectional shape, they are divided into round, square, rectangular and special-shaped steel pipes; according to the material, they are divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; in the process of steel pipe production, in order to obtain a certain length of pipe, it is often necessary to use a pipe cutting machine to cut the steel pipe.

[0003] After searching, the Chinese patent publication number is CN217070944U, which discloses a pipe cutting machine. In order to facilitate the rapid positioning and cutting of round pipes of different lengths, a pipe cutting machine includes a pipe placing frame and an inclined frame fixedly connected to the upper side of the pipe placing frame, a long hole is provided on the left side of the inclined frame, and a plurality of round holes are evenly arranged on the right side of the inclined frame, and a movable frame is movably connected to the long hole on the left side of the inclined frame.

[0004] The prior art is similar to the above-mentioned pipe cutting machine. During cutting, the cutting blade cuts the steel pipe downward from an angle until it is cut off. In this cutting method, both ends of the steel pipe need to be firmly fixed, otherwise the steel pipe is easy to deviate during cutting, resulting in an uneven cut surface. Therefore, there is room for improvement. Utility Model Content

[0010] Through the above technical scheme: when in use, the steel pipe to be cut is clamped and fixed by the steel pipe clamp, and the rotating sleeve is rotated. The rotating sleeve rotates to drive the threaded rod to move upward, and the threaded rod moves upward to drive the sliding ring to slide upward in the guide frame. The sliding ring moves and drives the entire cutting machine to move upward until the cutting blade is about to touch the steel pipe. The cutting machine is turned on, and the cutting machine drives the cutting blade to rotate at high speed. At this time, the cutting machine is slowly rotated, and the roller will roll along the guide ring. When the roller moves out of the groove, the position of the roller will be instantly raised. At this time, the pushing column pushes the pushing ring to move upward, and the pushing ring drives the sliding ring to move upward. The sliding ring drives the cutting machine to move. At this time, the cutting blade will be embedded in the steel pipe to cut through it. When the roller rotates around the guide ring within one circle, the cutting blade can cut 360 degrees around the steel pipe until the steel pipe is cut off. The cut surface is relatively smooth, which improves the cutting quality of the steel pipe.

[0011] The utility model is further configured that an adjusting handle is arranged on the top of the rotating sleeve, and anti-slip grooves are arranged around the adjusting handle.

[0021] The utility model is further configured that rotating handles are provided on both sides of the cutting machine, and the outer walls of the rotating handles are provided with anti-slip silicone sleeves.

[0022] Through the above technical solution: the setting of the rotating handle can facilitate people to hold the rotating handle to rotate the cutting machine, thereby improving the convenience of operation.

[0023] The beneficial effects of the utility model are as follows: when the planetary pipe cutting machine is in use, the steel pipe to be cut is clamped and fixed by the steel pipe clamp, and the rotating sleeve is rotated. The rotating sleeve rotates to drive the threaded rod to move upward, and the threaded rod moves upward to drive the sliding ring to slide upward in the guide frame, and the sliding ring moves to drive the entire cutting machine to move upward until the cutting blade is just about to touch the steel pipe, and the cutting machine is turned on. The cutting machine drives the cutting blade to rotate at high speed. At this time, the cutting machine is slowly rotated, and the roller will roll along the guide ring. When the roller moves out of the groove, the position of the roller will be instantly raised. At this time, the pushing column pushes the pushing ring to move upward, and the pushing ring drives the sliding ring to move upward. The sliding ring drives the cutting machine to move. At this time, the cutting blade will be embedded in the steel pipe to cut through it. When the roller rotates around the guide ring within one circle, the cutting blade can cut 360 degrees around the steel pipe until the steel pipe is cut off. The cut surface is relatively smooth, thereby improving the cutting quality of the steel pipe. BRIEF DESCRIPTION OF THE DRAWINGS
